Action Potential Generation and Propagation — Flashcards

In the muscle stretch reflex, stretch increases afferent impulses via _____ and II nerve fibers

Resting membrane potential of a nerve fiber is equal to the equilibrium potential of _____  and is _____mV.

Resting membrane potential of a _____ muscle is -90 mV

What kind of muscle fibres have more diameter? (fast or slow twitch)_____

In muscle contraction, after the muscle cell is depolarized, the action potential travels down the _____ and to the dihydropyridine receptor

When the membrane potential is _____ mv the inactivation gate of Na+ channel is closed

Sympathetic stimulation (norepinephrine) of a smooth muscle produces _____ potentials and relaxation.

Chemical Events during Muscle Contraction: No answer _____

Slow twitch muscle fibers are _____ due to increased myoglobin concentration

Hint: (color)

_____ is absent in smooth muscle but present in skeletal muscle

Hint: Micro-component
